In this case the torpedo vessel steers in for the bow or quarter of
the vessel attacked, according to the direction of the current, and on
the side approached launches the torpedo between the moorings as at A;
leaving the tow-rope slack, the torpedo vessel proceeds ahead or astern
against the current, and when at a sufficient distance off, the tow-rope
is held fast, which will cause the torpedo to diverge into contact with
the vessel attacked, as shown by the drawing.
